I'm relatively new to TRP (a couple months of daily reading, practice, etc.) I've had success with a couple plates since I've come home from college for the summer. I'm looking for some advice on in particular though. I went out to lunch with a friend at a local bar. A girl we ok new from highschool was waitressing. She had blown me off in highschool but since then I've gone from a basement gamer beta to a triathlete (literally) and I'm in the best shape I've been in. My friend and I say down, had lunch, and paid. When we were on our way out the waitress stopped us to give me her number and told me to text her to hangout sometime. I shot her a text a couple hours later to give her my number too and she struck up a conversation. She was still working and it was getting busy so she asked if she could text me after work. Told her sure and haven't gotten anything from her. I'm wondering of it would be better to wait and see if I get a text or if I'd be better of re-initiating things while there's still attraction from our run-in. Advice?

TL;DR: Ran into a girl from highschool waitressing at a bar I was at. She gave me her number unasked and told me to contact her to get together. Haven't heard from her since: wait or re-initiate while there's still momentary attraction?
